IPC: G02F1/133
Filed: 1992-01-20
Abstract: PURPOSE:To reduce the number of parts and provide an inexpensive luminance regulating circuit for back light which is easy to miniaturize. CONSTITUTION:A self-exciting resonance inverter 20 is formed including a transformer 30 and power transistors 32, 34 for converting an inputted direct current to an alternate current, and a switching transistor 36 for stopping the converting operation.

Filed: 1987-02-09
Abstract: PURPOSE:To prevent the outflow of an electrolyte from a container by forming recessed grooves on the inside of a vent plug, installing a guide wall which hangs from the vent plug toward a container, and forming recessed grooves on the inside of the guide wall. CONSTITUTION:Four recessed grooves 3 are vertically formed on the inside of a vent plug 2. A plurality of vertical recessed grooves 5 are also formed on the inside of a guide wall 4. During charging of a battery, gas evolves inside a container 1 and a part of an electrolyte is splashed, but splashes are trapped by the guide wall 4 and rarely enter the vent plug 2. Splashes which adhere inside the guide wall 4 and on the lower side of the upper wall 1a of the container 1 grow and fall along the recessed grooves 5 since the surface tension is decreased by the recessed grooves 5 of the guide wall 4. The outflow of the electrolyte from the container is remarkably decreased.
